A colleague's son is turning 13 in a couple of months and I'd like to get him a gift for the big teen transition. Problem is, I don't know what's cool among the early teen crowd these days. He's academically inclined but not a nerd, athletic (plays tennis, basketball, golf), not yet a typical hormonal teen (not really interested in girls yet and doesn't have that teen attitude). In his free time, he plays video games, drums, and takes sports lessons.
Those of you with sons this age - what are they into? TIA!
